Hi
I have a button on my page that does the following:
1. Reset a label control Me.lblError.Text = ""
2. Generates a PDF file on the server, if the PDF file fails to create because the user has supplied a serch that does not return any data the code exits and Me.lblError.Text = "some error message"
3. Downloads the PDF like this:
Response.Clear()
Response.AddHeader("Conten
Response.AddHeader("Conten
Response.ContentType = "application/octet-stream"
Response.WriteFile(file.Fu
Response.Flush()
Response.End()
My problem is that if the code perform a download the text in Me.lblError.Text is not set correctly....
That means that the error from the previous search is still there!
It looks like the postback is aborted after the response.flush/end during file download so that the label control is not updated!
I tried deleting the two lines:
Response.Flush()
Response.End()
but that did not help ......
How can I avoid this.

perform the resetting of the Label Using JavaScript where you run this command
Reset a label control Me.lblError.Text = ""
on the ClientClick of your button call a Javascript Function to change the innerText property of your Label.
eg:
<script language = "Javascript">
function resetLabel()
{
document.getElementByID(lb
}
</script>

You only get one response, you can use it to either change the label or to prompt the user to download the pdf, not both.
What I would suggest is writing some javascript that will hide the error when your download pdf button is clicked, that way you can still download the pdf.
Another thing you might want to do is open a new window when downloading the pdf.
